What is Beryl? - Pocket Guide to the Mineral Family of Emerald and Aquamarine

|Samina Gulzar

Beryl is considered one of the most scientifically important and commercially valuable gemstone minerals that gemology knows. It is an occurrence of naturally found beryllium aluminum cycosilicate, the crystalline structure of some of the most treasured gemstones in the world, such as emerald, aquamarine, morganite, heliodor, goshenite, and rare red beryl.

In a mineralogical perspective, beryl is characterized by its stable crystal chemistry, hardness, and the capacity to absorb a variety of trace chromophore components that give the gems a variety of gem colors.

Beryl may be scientifically defined as:

Technically, mineralogically, beryl can be characterized by a distinctly different hexagonal ring silicate structure that forms channels along the c-axis of the crystal. Alkali elements, water molecules, and trace metals may be hosted in these channels, which directly affect the color and optical properties.

Major scientific characteristics are:

Chemical Formula: Be3Al2Si6O18

Composition: Beryllium aluminum silicate occasionally containing some sodium, lithium, and cesium.

Variable Formula: (Be,Na,Li,Ce)3Al2Si6O18

Color: Light green- to emerald green, light blue- deep sky-blue, blue-green, yellow, pink, purple, red, orange, brown, colorless, white, and gray. May also be multicolored blue, green, yellow, or white.

Streak: Colorless

Hardness: 7.5 - 8

Crystal System: Hexagonal

Transparency: Transparent to opaque

Specific Gravity: 2.6 - 2.9

Luster: Vitreous, waxy

Cleavage: 3,1 - basal

Fracture: Uneven to conchoidal

Tenacity: Brittle

Other ID Marks: Sometimes fluorescent yellow, light blue, purple, pink, or red.

Complex Tests: Insoluble in acids.

In Group: Silicates; Cyclosilicates

Striking Features: Crystal form and hardness

Environment: Most famous of all the granite pegmatites is beryl. It is also present in mica schists that have been metamorphosed, and also in igneous deposits of rhyolites.

Rock Type: Igneous, Metamorphic

Popularity (1-4): 1

Prevalence (1-3): 2

Demand (1-3): 1

The hardness of beryl, combined with its abrasion resistance, makes it wearable over long periods, whereas the stable structure of beryl gives it the ability to maintain the clarity and color over long geologic and human periods.

Gemstone Varieties of Beryl

In its purest form, Beryl is colorless, but the element replacement within the crystal structure, which occurs in small traces, forms its gemstone types.

Aquamarine: Sky blue-bluish-green form of Beryl.

Bazzite: This is a mineral that is very similar to Beryl with a little of the rare element scandium, taking the place of some of the aluminum in the chemical structure of the mineral. It has a chemical formula of Be 3 (Al,Sc) 2 SiO 6. Despite the common belief that Bazzite is a kind of Beryl, it is a scientifically accepted fact that Bazzite is a separate mineral species.

Bixbite: Sometimes applied to Red Beryl that is uncommon in Utah. It was named after a mineralogist, Maynard Bixby (1853 -1935), who had explored the Thomas Range in Utah well known. The name Bixbite is no longer proposed and approved because of the confusion of the term with the mineral Bixbyite, which is a totally different mineral, named after Maynard Bixby.

Golden Beryl: Yellow variety of Beryl, which is golden yellow to orange-yellow.

Goshenite: Beryl, which is white or colorless in nature. Green Beryl: light shade of green Beryl. Green Beryl is contrasted with Emerald, which is darker green, and with Heliodor, which is greenish-yellow to yellow. Most of the authorities do not identify Green Beryl as a variety and instead classify it as a variant of Heliodor.

Heliodor: a variety of Beryl which is greenish-yellow to yellow. Light green, orange, and brown Beryl can also be referred to as Heliodor and can also be substituted with Golden Beryl.

Morganite: Pink -light purple form of Beryl. Additional information may be found in the gemstone Morganite.

Pezzottaite: Pezzottaite is a newly discovered raspberry-red mineral, and closely resembles Beryl Pezzottaite, only with lithium present in its chemical formula, in addition to the rare element cesium replacing some of the beryllium in its chemical formula. It is a newly discovered mineral, which was first recognized by IMA in 2003. Though Pezzottaite was initially considered to be one of the colours of Beryl, it has been scientifically considered as a separate mineral type.

Precious Beryl: Term applied to differentiate the gemmy transparent shapes of Beryl, as opposed to the more widespread opaque shapes.

Red Beryl: Deep red of Beryl, which is found in Utah.

How Beryl Forms in Nature

The beryl is created in particular geological conditions of high temperatures and the richness of minerals. It is commonly found in:

  • Pegmatite deposits
  • Metamorphic rocks
  • Hydrothermal veins
  • alluvial secondary deposits.

Key mines of Beryl Gemstones.

Some of the key beryl-producing areas in the globe include:

  • Pakistan: Swat Valley emeralds and deposits in the northern region.
  • Afghanistan: Panjshir emeralds and aquamarine.
  • Colombia: Famous emeralds in the world.
  • Brazil: aquamarine and morganite.
  • Zambia: Deep green emeralds
  • Madagascar: Beryl of different varieties.

Beryl as a Durable Jewelry.

Beryl gemstones are hard with a hardness rating of 7.5-8Mohs and are durable enough to be used in most types of jewelry.

Beryl is often used in:

  • Engagement rings
  • Pendants and necklaces
  • Earrings and bracelets
  • Collector gemstones
  • Custom jewelry projects

Treatments that are widely found in Beryl

Various kinds of beryl can be subject to treatments to increase their appearance:

  • Emeralds: Oil or resin filler to enhance clarity.
  • Aquamarine: Light heat treatment to increase blue color.
  • Morganite: Heat treatment to allow attainment of pink tones.
  • Uncut Beryl: The most precious and precious.

The grading of Beryl Gemstones

The beryl gemstones, and emeralds, in particular, are judged by:

  • Color: The greatest consideration.
  • Clarity: This is of the essence, especially in emeralds.
  • Cut: Deciphers brilliance and beauty.
  • Carat Weight: Stones of greater weight are rarer.
  • Origin: In most cases, the value is affected.
  • Status of treatment: Stones that are untreated attract premiums.

The Industrial Application of Beryl.

In addition to gemstones, beryl is a good industrial mineral, as it includes beryllium that finds application in:

  • Aerospace components
  • Electronics and semiconductors.
  • Metal and special equipment.
